Ticking 1HDT

Post by beanz2 »

Guys,

My 1HDT in my HJ75 has been making a ticking sound when it is cold. The sound seems to come from the Assisted Cold Start Device (ACSD), commonly callled the wax pellet. I live in a temperate climate and the winters don't get very cold here.

I've heard of suggestions to take the device out and use a plate from a 1HZ pump to cover the hole. Otherwise the part costs $400 from a Denso dealer.

Anybody done this on their 1HDT pump?

Dave

G'day Dave,
Apparently it's quite normal for the cold start mechanism to rattle, and won't do any harm. You can put your finger on the lever and it should stop the rattle and that will at least identify it as the source.
Damian.

should I swim it first ?

Hi Damian,

Indeed the ticking noise stops when the lever is pulled forwards. A diesel shop says if it breaks (how?) I'm in for a new pump. Any truth to this or is the shop trying to sell me a $400 part? But the same mob also said I can take a plate from a 1HZ pump and just close the opening.

Cheers,
Dave
